An audio processor 25 may include a codec, and the codec includes a data codec and an audio codec. The data codec processes packet data and the audio codec processes an audio signal such as voice and multimedia files, etc. Further, the audio processor 25 converts a digital audio signal received from a modem to an analog signal through the audio codec and then reproduces the analog signal, or converts an analog audio signal generated from a microphone (MIC) to a digital audio signal through the audio codec and then transfers the digital audio signal to a modem. Here, the codec may include a separate codec or may be included in the controller 10 of the portable terminal.

A memory 30 includes a Read Only Memory (ROM) or a Random Access Memory (RAM). The memory 30 may include a program memory and a data memory, and can store programs for controlling operations of the portable terminal and data for booting the portable terminal. The memory 30 may be an external memory such as a Compact Flash (CF), a Secure Digital (SD), a Micro-Secure Digital (Micro-SD), a Mini-Secure Digital (Mini-SD), an Extreme Digital (xD), a memory stick, etc.

The display unit 50 displays an image signal and user's data in a screen or displays data related to a call performance. The display unit 50 may include a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED), an Active Matrix Organic Light-Emitting Diode (AM OLED), etc. Further, the display unit 50 according to the embodiments of the present invention is implemented by a touch screen method and may be operated as an input unit, which controls the portable terminal, together with the key input unit 27. In general, the display unit 50 displays icons corresponding to applications, and menus and various information (e.g. electro luminescent information, battery information, time information, etc.) used for controlling operations (or functions) of the portable terminal in a display screen. A user can execute the application by touching the icon corresponding the application or control operation of the portable terminal by touching the menu.

A controller 10 performs a function of controlling the whole range of operations of the portable terminal. The controller 10 according to the embodiments of the present invention provides the user with an interface method in accordance with a request made by the user without the cumbersome of consecutively navigating different menu or submenus windows to identify a desired item, data, or function.

In operation, when the user touches a predetermined area of the display screen, the controller 10 generates a separate display area within the display screen such that one or more applications are displayed in the generated display area. When one of the displayed applications is dragged to move to the outside of the display area, the controller 10 controls such that at least one of data or functions, which are associated with the application dragged to the outside of the display area, is displayed within the separate display area. It should be noted that the separate display area may be expanded or reduced in size for display of the data or functions therein.

FIG. 2 is a flowchart illustrating a procedure of using a portable terminal according to an embodiment of the present invention, FIGS. 3A to 3D illustrate screens showing a first example using a portable terminal according to an embodiment of the present invention, FIGS. 4A to 4D illustrate screens showing a second example using a portable terminal according to an embodiment of the present invention, and FIGS. 5A to 5B illustrate screens showing a third example using a portable terminal according to an embodiment of the present invention. Note that in the embodiments of the present invention, the touch input or activation thereof includes an input of touching a touch screen and a drag input in which a finger moves on the touch screen while being in contact with the touch screen.

Referring to FIG. 2, in steps S201 to S202, when a user touches a predetermined area, the controller 10 generates a separate display area and controls such that one or more applications are displayed in the generated display area.

In step S201, as shown in FIG. 3B, the predetermined area touched by the user is a background area 320, in which icons 310 a to 310 d corresponding to applications operating in the portable terminal, menus (not shown), various information (e.g. electro luminescent information, battery information, time information, etc.), etc. are not displayed.

That is, the user can request that a separate display area be displayed as shown in FIG. 3C, by touching the background area 320 shown in FIG. 3B or in an area designed for such, in which the icons 310 a to 310 d displayed in a display screen 300 shown in FIG. 3A are not displayed. Therefore, when the controller 10 according to the embodiments of the present invention detects that the background area 320 is activated or touched by the user, the controller 10 generates the separate display area 330 as shown in FIG. 3C and makes a control such that one or more applications (or icons corresponding to the applications) are displayed in the generated display area 330.

As shown in FIG. 3C, applications displayed in the generated display area 330 include a camera-related application 331, a contact number-related application 332, and a memo-related application 333. Here, the applications 331 to 333 displayed in the display area 330 may be applications preselected (or preset) by the user or applications which have been executed more than a predetermined number of times.

According to the embodiments of the present invention, the user can preselect applications to be displayed in the display area 330 when the user touches the predetermined area 320 (for example, background area). Further, according to the embodiments of the present invention, the user can set that a predetermined number of used (executed) applications (e.g. top three applications frequently executed) to be displayed in the display area 330.

In steps S203 to S204, when the user drags any one among the displayed applications to the outside of the display area 330, the controller 10 makes a control such that at least one of data or functions provided by the application dragged to the outside of the display area 330 is displayed.

After the user touches the application which the user desires to execute, the user can identify (search for) the data or the function provided by the corresponding application through the touch input of dragging the application to the outside of the display area 330.

For example, the user can touch the contact number-related application 332 among applications displayed in the display area 330 and then drag the contact number-related application 332 to the outside of the display area 330 as shown in FIG. 3D. Through such a drag, the user can request that the data and/or functions provided by the contact number-related application 332 be displayed in the display area as shown in FIG. 4A.

In FIG. 4A, 332 a to 332 c indicate data lists of communication counterparts of which the names begin with letter “A”, letter “B”, and letter “C”, respectively, 332 d to 332 f indicate data lists of communication counterparts of which the Korean names begin with letter “

”, letter “

”, and letter “

”, respectively, 332 g is a function capable of adding a new contact number among functions provided by the contact number-related application 332, and 332 f is a function capable of editing the existing contact number among functions provided by the contact number-related application 332.

FIG. 5A illustrates the case, in which when the camera-related application 331 shown in FIG. 3A is dragged to the outside of the display area 330, functions 331 a to 331 d provided (or supported) by the corresponding application are displayed in the display area 330. FIG. 5B illustrates the case, in which when the memo-related application 333 shown in FIG. 3D is dragged to the outside of the display area 330, data 333 a to 333 d and a function 333 e provided by the corresponding application are displayed in the display area 330.

Meanwhile, in step S203 according to the embodiments of the present invention, it is assumed that the user continuously performs the touch input in the display screen 300 without removal (e.g. user's finger is kept being in contact with the display screen) after dragging the application, which the user desires to execute, to the outside of the display area 330. Alternatively, the user can release the touch input after dragging the application for a subsequent touch input activation within the display area 330.

Thereafter, in steps S205 to S206 when a continued touch input is made after dragging the application outside the display area, the controller 10 determines whether a touch input is terminated after pointing to one of data 332 a to 332 f among data displayed in the display area 330. If so, the controller 10 makes a control such that the existing data or sub items (see FIG. 4 c) are displayed in the display area 300.

Similarly, in step S207 to S208, the controller 10 determines whether a touch input is terminated after pointing to one of functions 332 g and 332 f among functions displayed in the display area 330. If so, the controller 10 makes a control such that sub items (not shown) associated with the activated function is displayed in the display area 300.

The user can identify the data or execute the function by selecting any one among the data 332 a to 332 f and the functions 332 g and 332 f shown in FIG. 4A. Steps S205 to S206 correspond to a process of requesting a data identification by the user, and steps S207 to S208 describe a process of requesting a function execution by the user.

In the embodiments of the present invention, the user can request the data identification or the function execution by dragging his/her finger to the data or the function, which the user desires to identify or execute, and then taking his/her finger off the data or the function. That is, according to the embodiments of the present invention, the controller 10 identifies that the identification of the corresponding data is requested if the touch input on the data is terminated, and the controller 10 identifies that the execution of the corresponding function is requested if the touch input on the function is terminated.

Referring to FIGS. 4B to 4D, the user drags his/her finger to the data list 332 a and then takes his/her finger off the data list 332 a (the touch input is terminated at the data list 332 a), so that the user can request the identification of the data list 332 a (i.e, sub-items), in which the names begin with a letter A, from the contact number-related application 332, and in response to the request by the user, the controller 10 displays the lists of communication counterparts, of which names begin with a letter A, as shown in FIG. 4C. Subsequently, the user selects any one (e.g. list 332 a-4) among the communication counterpart lists displayed in the display screen 300, and the controller 10 displays personal information of the selected communication counterpart (e.g. Andrew Blake) in response to the selection by the user as shown in FIG. 4D.

Meanwhile, in the embodiments of the present invention described above with reference to FIG. 2, the user takes his/her finger off the touch screen only one time while the data, which the user desires to identify, are displayed or the function, which the user desires to execute, is executed. The touch input (e.g. as shown in FIG. 3D) used when the user drags the application to transfer to the outside of the display area is considered to be kept in a touch state until the termination of the touch input by the user (the termination means that the user takes his/her finger off the touch screen as shown in FIG. 4B).

That is, the user drags a predetermined application to the outside of the display area 330 and keeps his/her finger being in contact with the touch screen until data or functions provided by the application dragged to the outside of the display area 330 are displayed. Thereafter, the user drags his/her finger to the data or the function, which the user desires to identify or execute, and then takes his/her finger off the touch screen, so that the user can request data identification or function execution.

According to the embodiments of the present invention, it is not necessary for the user to perform the touch input (e.g. an act of touching the touch screen) several times in order to identify (display) the data or execute the function, and it is possible to identify the data or execute the function by only performing the drag input and then taking his/her finger off the touch screen.

As described above, the present invention enables users to easily search for data and execute applications in portable terminals.

The above-described methods according to the present invention can be realized in hardware or as software or computer code that can be stored in a recording medium such as a CD ROM, an RAM, a floppy disk, a hard disk, or a magneto-optical disk or downloaded over a network, so that the methods described herein can be executed by such software using a general purpose computer, or a special processor or in programmable or dedicated hardware, such as an ASIC or FPGA.
